The original plans for the euro notes and coins envisaged that all of them should show some national symbols, for example the French Marianne, the German eagle, and of course in the UK the Queen's head.

But whether or not Britain signs up for the single currency, the Queen's head will now not appear on euro banknotes, following a decision by the European Central Bank in September 1998 to keep to a standard design across Europe.

The reverse of coins, however, will show some national symbols. In Ireland, for example, the Irish harp, in Spain a portrait of the King and in Finland a simple flower.

If the United Kingdom should join Europe's monetary union, then the Queen's head will be displayed on euro coins minted by the Royal Mint.
